4 Dnepr is currently best choice Working on more detailed cost analysis Difficult to get accurate cost info Actual cost of entire Dnepr is still not known May be cheaper to get ride on Arianne 5 Launch Vehicle Progress Mission System End Fall 08 Sub System Interface End Spring 09 2 Iterations 4

5 Fall 2008 Milestones Analysed various orbital strategies MatLab generated ballpark ΔV Attained STK Licenses Orbital Dynamics Progress Mission Fall 2008 Conclusions Maximum payload to moon via Direct Accent / Hohmann Transfer Future Requirement Model full mission via STK System End Fall 08 Sub System Interface End Spring 09 4 Iteration 5

6 Transfer Vehicle Progress Major Systems Evaluated Propulsion System Electrical Power Generation System Mission System End Fall 08 Sub System Interface End Spring 09 3 Iterations 6

7 Fall 2008 Activities: Propellant Survey Propellant / Structural Mass Comparison Trajectory / Propellant / Structural Mass Comparison Conclusions: Propellant Type MMH / MON Trajectory Type Direct Ascent 7

8 Goals for Spring 2009: Finalize Trajectory Finalize Propellant Type Design Propulsion System 8

9 Fall 2008 Activities: Researched different power generation methods Analyzed on power per mass and volume Conclusions: Solar cells are ideal for a long mission Batteries are sufficient for a short mission 9

10 Goals for Spring 2009: Determine actual power requirements of transfer vehicle Make final decision which power generation system will be used, provide design specs. 10

11 Goals for Spring 2009: Design transfer vehicle around Dnepr Space Head Module Determine transfer vehicle / lander configuration Conceptual integration of launch vehicle, transfer vehicle, lander and rover 11

12 Fall 2008 Activities: Propellant Survey Hard impact landing analysis Lander Progress Mission Conclusions: Hard landing requires large cushioning mass & volume Soft landing utilizes minimal propellant Soft landing will be used System End Fall 08 Sub System Interface End Spring 09 2 Iterations 12

13 Goals for Spring 2009: Calculate fuel requirements for soft landing Select Propellant Type and Engines Propulsion System & Control Concept Lander/Rover integration design 13

14 Sub Systems: Mobility System Power Generation System Camera Systems Radiation 14

15 Fall 2008 Activities: Compared two suspensions systems Kinematic analysis of rocker bogie system Analyzed traficability of rover on lunar surface. Conclusions: 4-wheel Rocker-Bogie is best Mobility System Progress Mission System End Fall 08 Sub System 2 Iterations Interface End Spring 09 15

16 Fall 2008 Activities: Determined panel output requirements given preliminary power budget. Selected SpectroLab s Triple Junction Solar cells. Created MatLab code provides size and weight of panels given a power requirement at any angel of incidence. Power Gen.
